A suicide bomber detonated a vehicle rigged with explosives at a police checkpoint in central Iraq on Monday, killing 10 people, an officer and a medical source said. The blast, which hit the Suweirah area, South of Baghdad, also wounded 35 people, AFP reported. The attack came a day after violence in Iraq, including a suicide bombing at a university in Baghdad, killed at least 16 people. The violence comes less than 10 days before the April 30 parliamentary. It will be the first parliamentary election since American troops quit Iraq at the end of 2011. Violence has killed at least 490 people in Iraq this month and upwards of 2,700 this year, according to AFP figures based on security and medical sources.
